An injection molding apparatus including a mold and an injection device is provided. The mold includes a fixed portion and a movable portion. A molding concavity is formed between the fixed portion and the movable portion, and the movable portion is adapted to move relative to the fixed portion to change a volume of the molding cavity, so that a pressure inside the molding concavity is adjusted between a pressurized state and a non-pressurized state. The injection device is adapted to inject a material into the molding concavity. The material includes a supercritical fluid, the supercritical fluid is prevented from being gasified in the pressurized state, and the supercritical fluid is gasified in the non-pressurized state. In addition, an injection molding method is also provided.

The present invention provides a method for producing a durable semispherical shoe which can be prevented from being subjected to seizure even in a dry lubrication state in which there is no lubricating oil at a start time of an operation of a swash plate compressor, can be restrained from deteriorating in its lubricating property due to generated frictional heat, and can be restrained from deteriorating in its strength at a production time and an injection molding die. A semispherical shoe (4), for a swash plate compressor, to be produced by the production method has a base material (5), consisting of a hard material, which has a hollow part along a central axis thereof and a resin layer, consisting of a resin composition, which is formed on a surface of a planar part, disposed on a periphery of the base member, which is to be subjected to sliding contact with the swash plate and on a surface of a spherical part, disposed on the periphery thereof, which is to be subjected to sliding contact with a piston. A resin-filled portion (8) where the resin composition is filled and an empty portion where the resin composition is not filled are formed in the hollow part of the base material. The resin-filled portion (8) and the resin layer are formed by injecting and filling the resin composition into a portion to be formed as the resin-filled portion (8) with the base material (5) being disposed inside a cavity (22) of the injection molding die.

In a molding die, movable die elements are respectively received in die element receiving holes formed in a frame plate. An end surface of the frame plate, which faces a cavity at a location that is other than locations of the die element receiving holes, forms a frame portion compression surface. An end surface of each movable die element, which faces the cavity, forms a split compression surface. Die element drive devices respectively drive the split compression surfaces of the movable die elements. A whole compression plate commonly supports an opposite end part of the frame plate and opposite end parts of the movable die elements, which are opposite from the cavity. When the whole compression plate is moved forward, the whole compression plate integrally drives the frame plate and the movable die elements forward. A whole drive device drives the whole compression plate.

A method for producing components or profiles from at least one solidifiable plastic mass in an injection moulding facility, said method comprising stationary mould components and mould components which are movable with respect thereto. The method includes injection of solidifiable plastic mass into a runner formed in the movable mould components and, from there, via connections either in portions into one or more mould cavities. The runner is enclosed by at least one stationary, temperature-controlled mould component. A continuous runner mass strand is formed with attachment mass strands, which is transported away from the casting site with increasing cooling and solidification and increasing length, together with the filled mould cavities and mould cavity portions. The runner mass strand, together with the connection mass strands, after its solidification and after opening the mould cavity or the mould cavities is separated from the component(s), and the component or the components is/are ejected.
